EARTHWORK AND GRADING
IN MINNESOTA
What is earthwork and grading
Earthwork and grading is the process of preparing a site for construction by reshaping, leveling and compacting the soil.
Construction sites must be graded so that water can flow away from buildings and other structures to avoid flooding. It also ensures even ground levels for constructing foundations. Earthwork is often accompanied with grading of landforms such as ditches, berms or embankments which are used to channel water flow away from an area. A ditch could be dug across a slope to carry surface runoff into a nearby river or stream; an embankment might be built near a roadway where it intersects with another slope in order to hold back floodwaters during heavy rainfall events. A berm may also be constructed along a shoreline next to undeveloped land in order to hold surface runoff water out of the way during construction activities.
Grading road surfaces can involve scraping or brushing off loose particles so that new bitumen, asphalt, concrete or stone aggregate can be added and compacted to form a strong, dense bond.
What is grading a site?
Grading a site involves the process of leveling the ground and moving soil to create a surface that is more even. This creates a flat construction site where a foundation for a building will be able to be laid. It also ensures water drains away from buildings and other structures to avoid flooding. Grading landforms such as hills, berms, or embankments can be done in order to channel water away from an area.
Earthwork and grading helps make construction sites safe, even, and functional for anything from commercial homes to industrial plants.

What is the difference between grading and earthwork?
A site needs to be graded so that all dangers are assessed and according to regulations prior to construction taking place. Earthwork involves the process of reshaping, leveling and compacting soil to create a flat surface for building foundations.
What is the difference between grading and land shoring?
Land shoring is typically categorized by supporting excavation walls with wooden planks or steel piles that are driven into dirt or clay. Land shoring is limited in the amount of support it can provide. Grading and land shoring often go hand in hand, with grading done before land shoring takes place and vice versa.
What is the difference between site grading and soil erosion?
Site grading helps make construction sites safe, even, and functional for anything from commercial homes to industrial plants. Soil erosion is a natural process or human-induced process of soil removal from one location on the landscape. It often leads to serious land degradation and is exacerbated by deforestation, drought, flooding, desertification and poor agricultural practices.
What is a good soil for grading?
A good soil for grading is free draining with a low water table. A sloping topography helps to divert water away from buildings and other structures.
Types of soil:
A site grading plan is an initial plan for building a construction project. The site should be graded so that all dangers are assessed and according to regulations. Before starting any type of earthwork it is key to first determine the types of soils on-site. There are three types of soils:
- Cohesive Soil- Type of soil where particles adhere together and can hold its shape when removed from the ground, also referred to as sticky soil.
- Granular Soil-A type of soil that is composed of small round pieces or particles and does not stick together in a mass when it is removed from the ground.
- Fragile Soil- A type of soil that can be easily removed in large quantities when it is dry, however when wet it becomes very strong and clay-like.
